A new method for single‐phase high resistance grounding fault protection in low resistance grounded distribution networks

Engineering Reports
The neutral point of the distribution network is grounded with low resistance, which can quickly remove single‐phase grounding fault and effectively suppress overvoltage. However, the existing zero‐sequence overcurrent protection has a high setting value.
